Keith Wall commented on QPID-7436: ---------------------------------- Attaching patch containing experiment with deleting message instances using a cursor, rather than individually. The performance improvement for BDB was negligible. > Improve the speed at which large queues can be cleared > ------------------------------------------------------ > > Key: QPID-7436 > URL: https://issues.apache.org/jira/browse/QPID-7436 > Project: Qpid > Issue Type: Improvement > Components: Java Broker > Reporter: Keith Wall > Fix For: qpid-java-7.0.0 > > Attachments: bdb_cursor_dequeue_message_instances.patch > > > Currently clearing a large queue takes a considerable length of time. This > can increase the recovery time of an application trying to recover from a > production incident. > The store should have the ability to perform something analogous to a > database {{TRUNCATE TABLE}} to quickly remove all entries on a queue. It may > be necessary to temporarily suspend enqueues to a queue whilst the operation > is ongoing. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
